Commonality between NMA and NSA? I am not sure it's not an NSA in disguise! They are talking 228 pax and 4,500 nm.Well that's a one class 240-250 seater which is what the A321neo is and the range is the same give or take what the A321XLR proposal is. The difference is two fold.It can take cargo at t...Jump to post
Flew out of Tarbes in France yesterday.I imagine that is the airport the above article is referring to.There were 3 A380's there.More impressive was the 'fleet' of A340's of all different types.-perhaps 20 odd.Also passed an A380 in a sort of lay by in 6 different parts about 20 miles inland.Jump to post
A lot has been spoken about Emirates limited taking off slots.Indeed they have themselves ! And it's not just slots per se they have to be a roughly the right time for decent one stop connections. But it's ( much) worse than that.They have been very limited -by many countries wishing to constrain Em...Jump to post
As no doubt most have read they have put Hubble in a passive mode whilst they work out a revised (and final?) strategy on how best to use the remaining gyroscopes.

Of course they said the A380 isn't profitable ( note the difference) ! What would you say to the only client ( but a very large one) in town.IE ( This is our bottom price ).BTw They didn't say manufacturing it was loss making they said they hoped they could break even at that reduced rate/price whic...Jump to post
It's hard to see what Emirates can squeeze.Airbus are not making profits out of the A380 at this production rate and neither will RR with the T900.Both could easily walk away with v little downside one imagines both programs are written down by now.Yes of course the T7000 would be nice bit it would ...Jump to post
Perhaps Emirates doesn't want the order because it's about to take over its next door neighbour? They've got plenty of 380's and plenty of other stuff on order!
It's gonna happen some time it's only a question of when (imho).
Tesla is very good at selling cars at a loss.Norwegian is also very good at selling airline tickets at a loss.The same fate will befall both of them.
Making money is the tricky bit!
I note the race to colonise the moon just got a third entrant.

Perhaps they changed their mind?
As suggested the worst known 'secret' the BE-4 has been chosen.So they are now in the hands of Mr Bezos Hmmmm. Odd thing ( to me) is that the BE-4 is designed from the ground up indeed inception as a reusable engine,yet here they are planning to throw them away each time (Unlike Blue Origin).Makes n...Jump to post
I am afraid I agree with Seahawk (thread closure) and the associated link from Reuters. We already know almost exactly what Airbus 'had' been showing clients and yes it included the 320 small stretch along with the same for the A321neo (and a further bigger rewinged )proposal.All have been publicly ...Jump to post
It certainly seems that interest and possibilities thrown up by the LR such as this,has spurred Airbus on very quickly to the XLR.Clearly plenty of interest in those extra 500nm.This requirement is well documented for TATL such as LH but no doubt the extra range opens up other possibilities elsewher...Jump to post
Well...We know BA wanted 6 more A380's.God knows the WW slanging match has been going on long enough.So perhaps the first question should be if not for NY where were these so badly desired A380's destined? Some/must have to have been for NY to replace the last of the 744's that fly there (super high...Jump to post
Good post and yes,for one,I believe it.

Not withstanding that Boeing's commercial launch programme is in tatters (ULA).Yes the...Jump to post
I agree it should really.However since I'm here! Above we read that the Airbus engineers consider the T7000 wrong for any possible NEO ( that we all know. Won't come - however).The reasoning is that the core is oversized for the requirement -really? I do understand that any 'cropped fan' engine has ...Jump to post

It's developing into a very interesting situation.It appears (appears) you have Boeing/Lockheed/ and NASA on one side of the equation and Spacex on the other. The former are addressing the Presidents directive to create an (elliptical) orbiting moon space station which will both put 'boots on the Mo...Jump to post
Return on capital employed.Hard to know exactly what Airbus' next big investment will be.

Really? I would suggest that there is zero chance of a stretch.Airbus is a business and there is no business case whatsoever so clearly it won't happen. They have been asked for a re engine by Emirates.They have received a flat 'no' for exactly the same reason - the investment would not yield a prof...Jump to post
Boeing patented their ovoid fuselage a long while ago now (8 years?).To have even got to that stage they will have done a huge amount of validation work.Obviously they have had all the time since then to fine tune the design ,so it unlikely to represent a timing roadblock. However this is not the sa...Jump to post
I never understand why these airlines (and I include Emirates) don't offer a premium class.It clearly is a moneymaker across the globe -particularly as Y has become 'thinner and thinner' on the whole.It could be a 'premium minus' at 8ab with 18.5" seats and extra legroom to a 'premiumplus' at 7...Jump to post

Sorry just saw this ,answers the question.No prototyping.Grasshopper tests instead with full BFS.
Yup that's correct.My point was that this method of 'trial and error' v nearly bust the company.With something like the BFS it surely would do ( if it had a similar early failure rate).Not only financially but also that clearly no one would want to get in it! NASA did many many years of study and pr...Jump to post
As a total amateur it seems ( to me) that they have accepted that the shuttle route of scrubbing of speed/energy was and is still the best route.The obvious difference is that their craft does not need to 'fly' as it touches down using 'their' vertical rocket engine powered route -which they know an...Jump to post
'Quickest reaction is for Airbus to scale up the A321' They already have. Their simple first solution was to offer a higher gross weight and slightly higher powered engines couples with triple belly tanks.This offers airlines greater seating capacity and greater range than the 757-200.The 321 LR.

It maybe that Airbus don't actually 'want' to 'go there'.Much of what has leaked out so far suggests they may not. The 'LR' requires no new engine,the XLR requires no new engine (but can achieve 4.5knm -200 2 class pax).The 'plus' doesn't require a new engine either as that is trading a small stretc...Jump to post
Re bigjku 'I think a big part of the business case, in the US at least, will be transcontinental and hub to hub movements.'

Such a shame really.

As stated it's a good start.It isn't a question of If but when as it has to happen.
I suppose most of this junk will fall back and burn up sometime of its own accord but don't know the projected time span ( obviously all different) of the majority.
I must go back and re look! I did notice later one of the illustrations refers to the ring of 'black boxes - it now appears' around the engine cluster.As additional cargo external holds.All a bit odd so maybe they will add more motors -who knows. Another illustration ( orbiting the moon) gives you s...Jump to post

Manoeuvring (above).I agree.Of course yes having wider three point landing legs will give greater stability on landing -particularly on unprepared lunar or Martian surfaces -so that's a plus right there.But that is a 'tail' not a (simple) fin.So it clearly has a use for manoeuvres-but of course we f...Jump to post
